First, back up everything now that is important to you especially this big project. Burn to a CD and for your project transfer everything important to a falsh drive so you can access it on another system.
Second, run memtest on your RAM. This is completely safe and free and will engage 2 seconds after you boot-up.
See the link below and follow the instructions. There is a newer version than what is listed but either one should work. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.
Let it run for a
LONG time. The rule is a
minimum of 7 Passes;
the more Passes after 7 so much the better. There are 8 individual tests
per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
